Definitions
- the present invention relates to soft-feel coatings for plastic substrates, [0002] BACKGROUND OF THE INVENTION
- Plastic substrates are generally low cost, durable and light weight; however, plastic is susceptible to being damaged by sunlight and weathering, impacts, and exposure to chemicals, including common chemicals found in lotions and insect repeilants,
- coatings have been developed for application to plastic substrates that are intended to protect the substrate and provide aesthetic value. More recently, coatings have been surfacing that not only protect the plastic surface but also impart a soft, grippy or rubbery feel to the otherwise hard plastic. These coatings have been generally branded with the term "soft-touch” or "soft feel” coatings.
- Soft touch coatings have been subject to increasingly demanding specifications as well. Particularly, soft-feel coatings are being challenged to have improved chemical resistance. The motivation driving this movement is evidence that many chemicals, including those found in lotions and insect repeilants, can soften the coating, and will migrate through the coating and into the plastic, causing adhesion loss of the coating to the plastic substrate and, in some instances, damage to the underlying plastic substrate.
- One approach to resolving this has been a multi-coating system incorporating a primer for chemical resistance and a soft-feel top coat. However, this multi-coating approach is time consuming.
- First-generation soft-feel coatings were largely solventbome polyurethanes based on blends of polyols and isocyanates.
- a typical waterborne soft touch formulation comprises a water dispersible polyol resin, often a polyurethane polyol dispersion and a water-dispersible isocyanate.
- the compositions may include other non-functional resin dispersions.
- Tg glass transition temperature
- WO/2012/089827 describes a polyurethane soft touch coating comprising the reaction product of a) a non- hydrolysable polyol binder, such as a polycarbonate or polyether polyol or polyester polyols having sterically hindered ester linkages, which are protected from hydrolysis, and b) and organic poiyisocyanate.
- a non- hydrolysable polyol binder such as a polycarbonate or polyether polyol or polyester polyols having sterically hindered ester linkages, which are protected from hydrolysis
- the present invention is based on the surprising discovery that certain pigments can be employed in wide variety of soft-touch coatings resulting in coatings that have substantially improved chemical resistance, particularly against lotions and insect repellents, and yet, retain their soft touch feel
- pigments are included in coating formulations to impart color or alter rheology in a particular manner.
- Many of the conventional pigments are amorphously or bead shaped and afford trivial hindrance to chemicals passing through the coating.
- a higher pigment load may offer greater nominal defense, but with potentially negative consequences to the overall feel of the coating due to the presence of the hard particles dispersed throughout the coating.
- many of the flake pigments also fail to impart sufficiently improved chemical resistance in soft- feel coatings, particularly as against chemicals in lotions and insect repellents, and so, do not pass current, stringent specifications.
- the pigments may themselves be pervious to chemical agents.
- flake pigments can have an exceptionally negative impact on the feel of the coating.
- Some flake pigments are susceptible to congregating at the surface of the coating or, by improper orientation in the film, interrupt the surface of the coating, giving it a hard and/or rough texture.
- Soft feel coatings that incorporate flattening agents along, to reduce gloss, and/or other bead or amorphous shaped pigment particles, when combined with flake pigments show susceptibility to poor chemical resistance and "feel". Without being bound by theory, it is believed that the amorphously shaped flattening particles in the coating can interfere with the desired horizontal orientation of the barrier pigments in the dry film, diminishing the effectiveness of the pigments to resist chemicals and potentially causing the pigments to interfere with the coating surface.
- these pigments have a sufficiently higher density relative to the wet coating resin matrix composition, are sufficiently chemically inert with respect to the coating compositions and are sufficiently impermeable, to allow the preferred pigments loaded in the range from about 5 to about 25% volume solids, to properly orient in the lower portion of the film layer, near the substrate, thereby improving chemical resistance, and sufficiently away from the upper surface of the coating so as not to inhibit the feel of the coating, This benefit may be seen both in flattened and non-flattened, pigmented and clear systems.
- Platelet shaped stainless steel flake pigments are particularly useful in producing metallic looking soft-feel coatings.
- Platelet shaped fluorophlogopite and calcined mica pigments are particularly useful in producing clear or pigmented soft-feel coatings.
- the present invention is directed to a method for improving the chemical resistance of a soft-feel coating composition that comprises incorporating into the soft-feel coating composition a barrier pigment, selected from the group consisting of platelet shaped (flake) stainless steel pigments, fluorophlogopite, and calcined mica pigments.

- the present invention is also directed to articles of manufacture comprising a plastic substrate to which at least a portion has been coated with a soft-feel coating of the present invention.
- the term "article of manufacture” is used in its broadest sense, and can include virtually any article comprising a plastic substrate and the soft feel coating according to the present invention.
- "Plastics” can include, for example, polycarbonate, acrylonitrile butadiene styrene polymer blends (“ABS”), thermoplastic polyolefms, polypropylene, magnesium, and/or mixtures thereof; "plastics” can be filled or unfilled.

- Stainless steel flake pigments impart a silver or metallic hue to the coatings and are particularly useful in preparing soft feel metallic looking coatings.
- Fluorophlogopite flake and calcined mica pigments are particularly preferred in preparing pigmented or clear soft feel coatings.
- the coatings of the present invention may include, in addition to a platelet shaped pigments selected from the group consisting of stainless steel flake pigments, fluorophlogopite pigments, calcined mica pigments and blends thereof, other conventional pigments to impart color or extender pigments.
- Representative such pigments may include, for example, titanium dioxide, carbon black, graphite, ceramic black, lamp black, antimony sulfide, black iron oxide, aluminum pastes, yellow iron oxide, red iron oxide, iron blue, phthalo blue and green, nickel titanate, dianisidine orange, dinitroaniiine orange, imidazole orange, quinacridone red, violet and magenta, toiuidine red. molybdate orange, and the like.
- Extender pigments such as amorphous, diatomaceous, fumed, quartz and crystalline silica, clays, aluminum silicates, magnesium aluminum silicates, talc, mica, delaminated clays, calcium carbonates and silicates, gypsum, barium sulfate, calcium zinc molybdates, zinc oxide, phosphosiiicates and borosilicates of calcium, barium and strontium, barium metaboraie raonohvdrate, and the like can also be incorporated.
- a useful feature of the coating compositions of the present invention is that they provide in a single coating a dry film having good adhesion to plastic substrates, improved chemical resistance and a soft feel.
- the coating composition herein may be applied by any conventional means to a portion or all of a plastic substrate.
- the compositions may be applied by spray apparatus, roller, brush, or dipping.
- One or more layers may be applied to the substrate wet on wet or wet on dry to a total dry film thickness of between 1 mil and 10 mils, although dry films in the range of 1 mil to 5 mils are desirable in some applications, and in others, from 1 mil to 3 mils.
- the substrate may be a portion of the interior component of a vehicle, such as a dashboard, steering wheel, knob, console or the like.
- the substrate may be a portion of a consumer or household product, such as a computer, electronic gaming or music storage and playback device.
- Example formulas 12-14 all formulations are in weight percent with respect to total formulation. Examples 12-14 are based on weight.
- Panels were measured for gloss at 60° using a gloss meter. For low gloss applications, a gloss measure of less than 5° is particularly desirable. The panels were ranked for feel by grip, slip, and softness. Chemical resistance was testing using GMW 14445 test for sunscreen and bug repeSiant resistance. For purposes of these evaluations, useful grip ratings were SM-M, slip ratings of SM-M, softness ratings of 7 to 10, and SB test results of 2.0 or lower on both smooth and grained portions of the panel,
- Fluorophlogopite demonstrates success at levels as low at 8% volume solids in soft feel coatings. Examples 10 and 1 1 illustrate some role of particle size. The volume solids were higher in the smaller synthetic fluorophlogopite (example 11), but chemical resistance was better in the larger particles size in example 10.
